Timing cover and drive

Timing belt, inspection

(15A-02)

Special tools: 885036

Remove the inspection hatch from the upper side of

the timing cover (A).

Make a temporary mark on the belt to ensure that

the whole belt is checked. Check the belt for wear

and damage and check that the belt is not split or

contaminated by oil. Turn the crankshaft so that all

the teeth on the belt can be checked. Replace the

belt if necessary, operation 15A-04. Remove the

temporary mark.

Press the ball end of the belt tension gauge and in-

stall the gauge over the belt. Ensure that the gauge

foot is located under the belt and between two teeth

(B). Slowly release the ball end and read off the

gauge. Turn the crankshaft slightly in each direction

until a stable read off is obtained. The correct value

for a new belt is 425-465 N and for a used belt 340-

370 N. If the tension of a used belt has fallen to 270

N or below, adjust the belt tension to 340-370 N, op-

eration 15A-03.

If belt tension is correct, install the inspection hatch

on the timing cover.
